How can 4 times 4 you find 4 times 40

answer:

it's hard to explain but i'll try. so you do 4x4 right? that's 16. so then to do 4x40 it's 4x4 again, but you add a zero since 40 is a multiple of 10 and has a 0.

step-by-step explanation:

step-by-step explanation:

4 x 4=16 and 4 x 40=160, so this is what i do i just take the zero from 40 in 4 x 40 and save it then i time 4 x 4=16 then the zero iv'e save i put it at the end of 16 to get 160

step-by-step explanation:

first, eliminate the parenthesis:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
